🚀 Getting Started (Local Development)

Frontend Microfrontends

  1. Install dependencies for all apps:
npm install
  1. Start the DSA remote microfrontend first:
cd microfrontend/apps/dsa
npm run start-mf
  1. Start the Host shell app:
cd microfrontend/apps/host
npm run dev
  1. Optionally start WebDev remote microfrontend:
cd microfrontend/apps/webdev
npm run dev

Backend API

  1. Navigate to API folder and install:
cd interviewpro-backend
npm install
  1. Create .env file with:
PORT=5000
MONGO_URI=your_mongodb_connection_string
  1. Start the server locally:
npm start

API will be available at http://localhost:5000.

📦 API Endpoints

Route Method Description
/ GET API landing page with overview
/api/react GET React interview questions
/api/js GET JavaScript questions (optional)
/api/dsa GET DSA questions (optional)

🛠️ Deployment on Vercel

Frontend

  • Each microfrontend app can be deployed independently or together.
  • Use Vercel dashboard to deploy each app (host, dsa, webdev).
  • Set environment variables if needed.

Backend

  1. Add vercel.json in /api:
{
  "version": 2,
  "builds": [
    {
      "src": "server.js",
      "use": "@vercel/node"
    }
  ],
  "routes": [
    {
      "src": "/(.*)",
      "dest": "server.js"
    }
  ]
}
  1. Set environment variables in Vercel dashboard:
  • PORT
  • MONGO_URI
  1. Deploy the API folder as a separate project in Vercel.

📌 Roadmap

  • Complete module federation with WebDev remote
  • Add Swagger/OpenAPI docs for backend API
  • Implement authentication & authorization
  • CI/CD pipelines for both frontend & backend
  • Add caching & rate limiting for API
  • Expand question sets and categories
